Sperm whales have huge heads they account for up to a third of their overall body length. Large brains paired with extreme amounts of folding or gyrification means things like language memory and emotional capacity are highly developed allowing orcas to develop rich culture. Sea lion mothers wail when watching their babies being eaten by killer whales.
Pectoral flippers are relatively short broad and paddle-shaped.

Dolphins and other toothed whales such as the beluga echolocate via a specialized organ called the dorsal bursae which sits at the top of their head close to the blowhole.

Polar bears live in the Arctic on ice-covered waters. Sperm whales have the largest brains. One thing all toothed whales have in common is their sophisticated sonar systems called echolocation.
Humans have very little hair compared to other primates. Humpback whales are massive growing up to 17 metres in length. Their upper dorsal body is primarily a dark shade of grey with distinct areas of white on their flippers pectoral fins and under ventral bellies.
While these cases have happened they are rare and only a handful of aggressive. Polar bears rely on sea ice to access the seals that are their primary source of food as well as to rest and breed. There are 40 extant species named as.
Blubber also helps provide buoyancy. Orcas have the second largest brain of any animal in the world. The two parvorders baleen whales Mysticeti and toothed whales Odontoceti are thought to have diverged around thirty-four million years ago.
The primary function of the tigers hair is for warmth. Body lengths of cheetahs range from 112 to 150 cm 393-492 ft tail lengths are between 60 to 80 cm 2-262 ft and the height at the shoulder ranges from 67 to 94 cm 22-31 ft.
